He-Ne Laser (Discontinued) - SE-9449A

This Helium Neon Laser has two advantages over other lasers:

1) 1.5 mW: The extra power makes laser experiments and demonstrations brighter (and often easier). It’s especially useful for holography. A shorter exposure time can be used to minimize problems with vibrations.

2) Modulation: Connect a microphone to this laser, and students can transmit voice through the laser beam to a distant receiver. Or use this laser as a laser stroboscope for timing.

Note: Additional equipment, not available from PASCO, is required for laser communication experiments.
